There is disclosed a set of decking boards comprising a first (100a) and a second (100b) decking board and being provided with a connecting system comprising a connecting device (200). The first board (100a) is configured to be connected to a support element (300) and the second board is configured to assume a vertically locked state with respect to the first board in which the connecting device cooperates with the first and second boards, there is a vertical gap (G) between a portion of the second lip (120) of the first decking board and a portion of the second lip (150) of the second decking board, and there is a horizontal space (S) between a first lip (110) of the first board and the second lip (150) of the second board. There is also disclosed other aspects of a set of decking boards and connecting devices as well as methods for demounting decking boards and replacing them with new decking boards.

The disclosure generally relates to flooring and decking. More specifically, the

disclosure relates to a set of decking boards provided with a connecting system

comprising a connecting device, such as a clip. The disclosure also relates to the

connecting device and a method of demounting a set of interlocked decking boards. 5 BACKGROUND

Decking is typically utilized as outdoor floor constructions in the vicinity or in

connection to a building. Decking panels are usually arranged at an elevated level

above a ground. The decking panels may be made of treated or composite lumber,

aluminium, or other materials. The decking panels may be installed by means of 10 separate clamps that are attached to a joist structure. The clamps hold the decking

panels in place and may define a uniform gap between the decking panels. Adjacent

decking panels may comprise overlapping lips, thereby concealing the joist structure

provided below the panels.

However, the decking panels in the prior art suffer from several drawbacks, 15 especially in the case when they are made of a relatively soft material, a low-quality

material, a cheap material, or a low-density material. Known panels utilizing separate

clamps and overlapping lips are hard or even impossible to demount without

damaging one or several panels. Indeed, in order to remove a panel, a portion of the

panel ordinarily has to be cut in order to be able to access the clamp. One reason for 20 this disadvantage is because the panels are arranged to be installed sequentially in

one row after another. According to methods in the state of the art, there is no

possibility to remove a panel in the middle of the sequence of panels without

removing all of the panels that have been installed subsequently in the sequence of

panels.25 As a consequence, a new panel that will replace a removed panel cannot be

installed in the same manner as the previous ones, since they require a sequential

arrangement. Thus, the new panel has to be installed by a different method, for

example by cutting it appropriately and fixing it by screwing or by gluing it to the joist

structure in an ad hoc manner. The first example may result in a less attractive 30


appearance of the panel, since screws may become visible, and the second example

may result in a panel which is not attached to the joist structure properly, since glue

may provide less fixation than screws.

Additionally, known panels utilizing separate clamps and overlapping lips typically

run the risk of being damaged when they are installed, since they are provided with a 5 rather weak groove and lip structure that are arranged to house the clamp. During

installation, a screw is screwed through parts of the weak structure and is provided

through the clamp. As a result, the weak structure may become deformed or even


Finally, panels installed according to known principles may become deformed due to 10 ...
